Once you’ve procured your network switch, it’s time to lay down the specifics of the network., The best kind of network to implement in a private LAN (like the one you are setting up) is known as a Class C network. Without getting into the specifics of IP nomenclature and architecture, a Class C network is one that is standardized for use within offices and private LANs, as opposed to those used on the Internet and other public networks.
Therefore, all computers that are part of this network will have to have their network cards configured in Class C mode. If your friends are already using a broadband Internet connection, they will already have a network card in their system. If not, they will need to buy or borrow one. With most modern computers, Ethernet functionality is integrated into the motherboard itself.
On D-day when your friends come over with their computers, they will need to set up their computers at the locations you tell them to, in accordance with where the power outlets and seating areas are. As far as possible, ensure that the computers are located around the region where your network switch is located. This will make it easier to string the Ethernet cables between each of the computers and the switch.
If you check the properties of your LAN card, you will see an IP address as part of the TCP/IP properties of the LAN card. This IP address will need to be changed to look something like 192.168.0.x. Here, the ‘x’ can be any number from 0 to 254. Each computer on your network will need to have a unique IP address, based upon this numbering system.
Finally, in the subnet mask field (also a part of your network card’s TCP/IP properties), set this to 255.255.255.0 for all the computers in this network. This value tells all computers that they are part of the same IP set and is required for them to exchange data between them. Check out the screenshot to get a clear idea of this network configuration.
It would be a good idea to print out all these networking and configuration details on flyers and hand them out to the participants to simplify the setup process. For larger LAN parties, print these configuration settings on a poster and place it in a visible area.
